RabbitMq Management plugin only on localhost

I solved it, my mistake was:

export RABBITMQ_CONFIG_FILE="/etc/rabbitmq/rabbitmq.config" instead of export RABBITMQ_CONFIG_FILE="/etc/rabbitmq/rabbitmq" in "/etc/rabbitmq/rabbitmq-env.conf"

It is not necessary to specify the extention ".config" of the file.

And in "/etc/rabbitmq/rabbitmq.config", I just kept:

[
        {rabbitmq_management, [
                {listener,[{port, 15672},{ip, "127.0.0.1"}]}
        ]},
]

The node: {kernel, [{inet_dist_use_interface,{127.0.0.1}}]} was creating some conflict, I took it away with no further investigation.
